I have a Cisco ASA 5510 ASA Firmware 8(x). It is my firewall/perimeter device for the network. Inside the firewall on the internal LAN, I have a terminal server box.
I want to allow users with the Cisco VPN client to connect via VPN and ONLY be allowed to connect to the specific IP address (a specific port on that IP would be even better) of the terminal server to log in using RDP.
I have 250 VPN user license and 2 webvpn licenses. The terminal server is a windows 2008 Standard server. I have no funds to buy any additional equipment, licenses or software. I am not able to set up a DMZ or change the IP address of the terminal server.
All suggestions are appreciated. Thanks in advance.
